Lululemon founder and billionaire Chip Wilson and his wife of over 20 years, Summer Wilson, have announced their divorce. With no prenuptial agreement in place, the distribution of their substantial assets remains to be clarified, and the market is watching for potential equity changes this event might trigger. Chip Wilson holds approximately 8.6% of Lululemon shares through his entities, valued at nearly $1 billion; Summer Wilson separately holds about 1% of shares, valued at approximately $100 million. This divorce comes as Lululemon's stock plunged over 17% this Friday due to a downward revision of its full-year sales outlook, currently hovering near an eight-year low.
